,of New York, have invented a new and Im- SPIKE-EXTRACTOR.

lSPECIFICATION forming part of Letters Patent No. 290,011, dated December 11, .1883.

`Application filed May T0 aZZ whoml it may vconcern,

Be it known that I, JOHN EBBER'I, of Rockaway Beach, in the county of Queens and State proved Spike-Extractor, of which the follow` ing is a full, clear,v and exact description.

The object of my invention is to provide a tool or implement for pulling nails or spikes easily and quickly. y

The invention consists of a pair of quadrantal toothed sectors pivoted to each other at the angles by a pair ot' links or radius-bars in a lmanner to permit and compel the engagement of the curved sectors with each other by mesh of their teeth, one of the sectors havingv a hook or claw for engaging the spike, pivotjointed at one end of its toothed rim, and a lever secured at the opposite end or side ofthe toothed rim, which lever may be worked to rock. its sector on the relativelystationary sector for raising the claw-head and extracting the spike.

The invention includes, also, a special construction of a supporting shoe or fulcrumblock in arched form, and with one side or leg support pivoted for swinging upward, to per-l mit resting the head of the fulcrumblock on a raised surface-such as a railway-rail-while avoiding contiguous Obstructions, the folding leg-support being adapted, also, .to be swung down to form, with the fixed leg or foot, a substantial support to the tool for working it in extracting spikes Afrom plane or flat surfaces, as hereinafter fully described andclaimed.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference in di cate corresponding parts in both the figures.

Figure l represents in side elevation and in full lines the tool as applied to start the embedded spike, the dotted lines indicating the positions of the parts when the spike has been fully drawn; and Fig. 2 is a front view with the extracting-claw shown raised and the parts in full lines.

a and b represent two quadrant-shaped sectors,toothedattheircurvedorperipheraledges, at c c, and in like pitch for engagement with each other, the throats or spaces ofthe teeth, preferably of both sectors, being sunken below the pitch-line ofthe teeth, to cause the points of the 5.18133. (No model.)

teeth to work between the side ribs or guards d, to thwart a tendency to lateral displacement, the sectors a b being pivoted or linked toeach other by the links or radius-bars e-one at each side-which connect the sectors by their angles at f, to permit and compel their teeth to mesh uniformly as the sector a is rocked over the` relatively-stationary one b by the stout lever g on sector a., for causing the hook or claw h, which is strongly pivot-jointed tothe sector av at i, to rise after the claw-head` h', preferably of the open-eye form shown has been swung'beneath the shoulders of the spike or nail head for withdrawing the embedded spike or nail, any suitable stop or detentd', being provided ou sector a to limit itsbackward swing and prevent disengagement of the sectors by contact with the edge of sector b, as in dotted lines in Fig. 2.

To support the sector b against the downward thrust on it ot' withdrawing the spike, I t it to a fulcruIn-shoe consisting of a headplate, 7c, having downwardly-projecting and fixed supporting legs or feet Z, which are placed apartsufficiently to permit the claw-head h to pass freely up and down between them, the

eXtreme lower end of the feet l resting on any base or surface-as a railway-tie-a little beyond a vertical line drawn through the center of the bars e and the mesh `of the teeth when the segmentsare in position `to engage the head ot' the embedded spike, as in full lines. Fig. 1, so that the line `of outer support of the tool in starting the spike of a railwayrail, t, will fall a lit-tlc outside of the claw-head, for more effective and steady action of the parts. The head-plate k is firmly bolted to the side b of sector b, which forms its base and finishes iiush on each side with the side edges of the segments, to permit the bars or links e to work past them to the horizontal position of Fig. l.

As thus far desciibed, the shoe It Z is completely adapted for supporting the device in conjunction with a railway-rail head or other surface raised sufficiently to act with the legs Z,- but it is desirable to adapt the fulcrum shoe or rest to support the tool independently of such rail-head or other raised surface, and to this end I pivot to the head-plate 7c, or on the same joint-pin which connects bars c with the sector b, the auxiliary bar or foot m, Which, with the shoe'k l, constitutes an arch or bridge capable of supporting the tool independently of any other rest therefor. y

It will be noted that by the pivotal connection of the foot m with the head-plate k or sec tor Z) said foot m may swing off freely beyond or'at the side of the rail opposite the claw h,

t6 permit the claw to be adjusted to railwayspikes at the edges of rail-base aillgs of different Widths, and to permit, also, a rockingof the head-plate k on the heads of rails t of different heights, while securing,` a lirni rest for the feet Z; and the pivoted foot m may also be swung up to or above a horizontal position, to avoid frog or switch points or other contiguous obstructions which would interfere with the proper support of the tool in pulling the spike, and when the tool is to be supported on the arch or bridge 7c Z on independently ot' a rail or other raised surface the foot m will gravitate to a. position for properly seating it- -selt`, as in dotted lines, Fig. 1.

It will be noticed, also, that the greatest lever- Aage is obtained when required in starting the spike, and that the action may be as rapid as desired in completing the Withdrawal of the loosened spike, the entire operation being quickly and easily performed.

Having thus described iny invention, I claini as new and desire to secure by Letters Patentl. A spike-extractor constructed with two in'terineshing` toothed sectors connected at the l angles by links or radius-bars, to one of which sectors is connected a working-lever, and a pivoted hook or claw for engaging the spike, the whole adapted to be sustained by a suitable support, substantially as shown and described.
